Marilyn Chambers—the Jenna Jameson of the '70s and '80s—was found dead in her mobile home on April 12. She was 57. Cause of death is unknown at this time. (Link NSFW.) [AVN]

She was "known" for bringing Daisy Dukes to the next level, purposely exposing her labia. Her film Insatiable was a porno classic, and she sang a song for the soundtrack, which we once used in an episode of Pot Psychology.
